LM234DT

STMicroelectronics · Current-Sensing Amplifiers · SOIC-8

LM234DT from STMicroelectronics, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ input Adjust pin. External current-set resistor (Rset) is connected between ADJ and V-; the voltage across Rset (~64 mV @ +25 °C) sets Iset. VADJ to V- absolute max is 5 V.
2 NC unconnected No internal connection.
3 NC unconnected No internal connection.
4 V+ power_in Positive supply / current input. Forward V+ to V- range 1 V to 40 V (LM234: 40 V max). Set current flows into this pin.
5 NC unconnected No internal connection.
6 V- power_in Negative supply / current output return. Set current flows out of this pin toward the load return.
7 NC unconnected No internal connection.
8 NC unconnected No internal connection.

CAD (KiCad official)

  • Symbol: LM234DT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm234dt-etched.step / lm234dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm234dt.step / lm234dt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm234dt.step 122 KB You want the bare part, or you mark your own boards.
lm234dt-etched.step 1.4 MB You want the part with LM234DT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 364 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (16 pp, sha256 8118b20a8e977dd1, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
